About this tool
This Password Generator creates strong, unpredictable passwords using your browser's cryptographically secure random generator. Choose the length and whether to include uppercase, lowercase, numbers and symbols, and get an instant strength rating. Strong, unique passwords are the single best defense against hacked accounts, and because generation happens locally, your password is never transmitted or stored.

Use generated passwords safely
Practical example
For an important account, choose at least 16 characters with mixed character types, then save the result directly in a trusted password manager. Generate a different password for every account.
Interpreting the result
Length and unpredictability matter more than memorable substitutions such as replacing an “a” with “@”. A random password protects best when it is unique and the account also uses multi-factor authentication.
Limits and common mistakes
A strong password cannot protect a compromised device, a phishing victim or an insecure recovery email. Never send the generated value through public chat or reuse it on another service.
